Installing Power365 Directory Sync Lite

Power365 Integration Projects can only be implemented if both the source and target tenants are synchronizing AD objects from their on-premises environment to Azure AD/Office 365. Power365 Directory Sync will make the appropriate changes to the local AD objects but Azure AD Connect or an equivalent 3rd party sync solution must sync those changes to Azure AD/Office 365.


What is Directory Sync Lite?

Power365 Directory Sync installs a Windows service named “Binary Tree Power365 Directory Sync Lite”. This service is the component that communicates with Active Directory and the cloud.


What options are available for installing Directory Sync Lite?

This service can be installed 2 different ways depending on the choice you make at installation time.

  • If you choose “SQL Authentication” the service will be installed to run as “Local System”
  • If you choose “Windows Authentication” the installer will prompt you for domain credentials and run the service as the specified user.

Run as “Local System” is the most common installation scenario but causes an issue if you require http proxy server routing. The service account is treated differently than regular user accounts and doesn’t generally pick up user proxy policy.

Proxy configuration can be done for the service account but is generally avoided.

The easiest way to use a http proxy server with Power365 Directory Sync is to change the service “Log On As” value to a domain user, and configure that user’s proxy information.
